Silent saw blade matrix

Abstract

The invention relates to a noise-damping saw blade matrix, which comprises a saw blade matrix. The centre of the saw blade matrix is provided with a central hole, noise-damping seams are distributed on the saw blade matrix symmetrically along the central hole, the beginning and the end of the noise-damping seams are provided with stop holes, and copper nails are embedded in the stop holes. The noise-damping saw blade matrix provided by the invention designs a structure of the stop holes on the beginning and the end of the laser cutting noise-damping seams so as to prevent kerfs from cracking because of over concentration of stress; the copper nails embedded in the stop holes are taken as a filling material so as to have good buffer function and reduce the probability of cracking on the stop holes; and simultaneously, different damping coefficients of copper and steel are utilized to reduce noise generated in the process of cutting a saw blade.

Description

technical field [0001] The invention relates to a sawing tool for non-metallic materials, in particular to a sound-absorbing saw blade base body which can reduce the noise during the use of the saw blade. Background technique [0002] Diamond circular saw blades are widely used in the processing of various non-metallic materials due to their superior cutting performance, but the saw blades will generate a lot of cutting noise during the cutting process, causing great harm to the operator and the environment harm. Aiming at the problem that the saw blade produces a lot of noise during the cutting process, a series of noise reduction measures have been studied. One is to use the "sandwich" technology to add composite materials between the two substrates to prevent the saw blade from resonating, so as to achieve the purpose of sound attenuation. This type of product has high safety, long service life, and the cutting noise can be reduced by more than ten decibels. However, th...

Problems solved by technology

This type of product has high safety, long service life, and the cutting noise can be reduced by more than ten decibels. However, the production process of this "sandwich" sound-absorbing saw blade is complicated, the production cycle is long, and the production cost is high.

Another kind of noise-absorbing saw blade is to precisely cut a special pattern on the steel substrate to prevent resonance during the cutting process of the saw blade so as to reduce or even eliminate noise, but this kind of saw blade is at the expense of the strength of the saw blade substrate To achieve a good noise reduction effect, the crack sensitivity of the saw blade is high, which reduces the performance of the saw blade and makes it difficult to ensure safe operation
